| Abstract | We studied experimentally whether horse dams influenced foals' relationships with humans. We investigated the influence of the establishment of positive human-mare relationships on foals' behaviour toward humans. Forty-one foals and their dams were involved in this experiment. Half of the mares were softly brushed and fed by hand during a short period (total of 1.25 h) during the first 5 days of their foals' lives (experimental group, n = 21). The other mares were not handled experimentally and their foals received no contact with the experimenter (control group, n = 20). The reactions of both experimental and control foals were recorded under various conditions, first, for 5 min in the presence of a motionless experimenter, when foals were 15 and 30-35 days old, then in an approach test when they were 15 days old and in a saddle-pad tolerance test when they were 30-35 days old. Finally, approach-stroking tests were performed successively by the familiar experimenter when foals were 11-13 months old and by an unfamiliar person when they were 13-15 months old. Several observations strongly suggest that mares can influence their foals' behaviour toward humans: (1) during the handling procedure, experimental foals of protective mares were further from the handler than foals of calm mares (p < 0.001); (2) experimental foals remained, at all ages, closer to the experimenter (p < 0.05) and initiated more physical contacts (sniffing, licking, etc.) with the experimenter (p < 0.05) than control foals; (3) avoidance and flight responses of experimental foals were considerably reduced during approaches by the experimenter (p < 0.01) and they accepted saddle-pads on their backs more easily (p < 0.01) and more quickly (p < 0.01) than control foals. Lastly, the consequences of handling mares had effects that lasted at least until foals were one year old (p < 0.05) and became generalized from experimenter to unfamiliar humans, who could approach and stroke experimental foals rapidly during a test (p < 0.05). This is the first report of an attempt to use observation of mother by foals to facilitate human-foal relationships. The procedure is simple, takes little time and can easily be applied to any dam-foal pair, as it is not intrusive and presents no risks of disrupting mare-foal bonds. | ||||

| Abstract | We studied molecular evolution of the mosquito-borne alphavirus Highlands J (HJ) virus by sequencing PCR products generated from 19 strains isolated between 1952 and 1994. Sequences of 1200 nucleotides including portions of the E1 gene and the 3' untranslated region revealed a relatively slow evolutionary rate estimated at 0.9-1.6 x 10(-4) substitutions per nucleotide per year. Phylogenetic trees indicated that all HJ viruses descended from a common ancestor and suggested the presence of one dominant lineage in North America. However, two or more minor lineages probably circulated simultaneously for periods of years to a few decades. Strains isolated from a horse suffering encephalitis, and implicated in a recent turkey outbreak, were not phylogenetically distinct from strains isolated in other locations during the same time periods. Our findings are remarkably similar to those we obtained previously for another North American alphavirus, eastern equine encephalomyelitis virus, with which Highlands J shares primary mosquito and avian hosts, geographical distribution, and ecology. These results support the hypotheses that the duration of the transmission season affects arboviral evolutionary rates and vertebrate host mobility influences genetic diversity. | ||||

| Title | Leader--Follower Effects in Resource Dilemmas: The Roles of Leadership Selection and Social Responsibility | Type | Journal Article | ||

| Abstract | Previous research on the allocation of scarce resources shows that when people are assigned labels of leader or follower in their group, leaders allocate more of the scarce resources to themselves than followers do. In three laboratory studies, we examine the idea that how people are selected for the leader role (i.e. election or appointment) determines whether leaders take more or equal shares (relative to followers) from a common resource. In a first experiment, we show that participants were more accepting of norm violating behavior by an appointed versus elected leader. In a second experiment, we show that when participants were assigned to a leader or follower role, allocations of appointed leaders differed significantly from those of elected leaders and followers, whereas there was no difference between the two latter conditions. Moreover, elected leaders were shown to feel more social responsibility than both appointed leaders and followers. In a final experiment, we show that when participants were primed with the concept of social responsibility (relative to a neutral condition) no difference in allocations between appointed and elected leaders emerged. | ||||

| Abstract | Brain asymmetry—i.e. the specialisation of each cerebral hemisphere for sensorimotor processing mechanisms and for specific cognitive functions—is widely distributed among vertebrates. Several factors, such as embryological manipulations, sex, age, and breeds, can influence the maintenance, strength, and direction of laterality within a certain vertebrate species. Brain lateralisation is a universal phenomenon characterising not only cerebral control of cognitive or emotion-related functions but also cerebral regulation of somatic processes, and its evolution is strongly influenced by social selection pressure. Diseases are well known to be a cost of sociality but their role in influencing behaviour has received very little attention. The present study investigates the influence of illness conditions as a source of variation on laterality in a social keystone vertebrate predator model, the lion. In a preliminary stage, the clinical conditions of 24 adult lions were assessed. The same animals were scored for forelimb preference when in the quadrupedal standing position. Lions show a marked forelimb preference with a population bias towards the use of the right forelimb. Illness conditions strongly influenced the strength of laterality bias, with a significant difference between clinically healthy and sick lions. According to these results, health conditions should be recognised as an important source of variation in brain lateralisation. | ||||

| Abstract | Gegenstand und Ziel: Überprüfung der Tiergerechtheit von Abrufstationen für Kraftfutter und Heu in der Gruppenhaltung von Pferden anhand ethologischer und physiologischer Parameter im Vergleich zu konventionellen Fressständen. Material und Methoden: Die Verhaltensbeobachtungen fanden in 11 bzw. 10 Offenlaufställen mit Abrufstationen bzw. Fressständen statt. 270 Pferde wurden individuell unterschieden. Untersuchungsparameter waren: Drohverhalten mit und ohne Verletzungsrisiko, Meideverhalten, Verdrängung aus dem Fressstand sowie Herzfrequenz und Integumentverletzungen. In jedem Betrieb erfolgten kontinuierliche Direktbeobachtungen für je einen 24-Stunden-Tag (Tortenstückverfahren). Ergebnisse: Im Wartebereich der Abrufautomaten traten signifikant mehr Drohgesten ohne bzw. mit Verletzungsgefahr je Pferd und Tag (8,6 bzw. 3,0) auf als im Wartebereich der Fressstände (3,4 bzw. 0,9). Demgegenüber konnten die Pferde in Abrufstationen (1,4 Drohgesten je Pferd und Tag) ungestörter fressen als in Fressständen (3,2 Drohgesten je Pferd und Tag). Insgesamt betrachtet ergab sich jedoch bei beiden Fütterungssystemen eine geringe Anzahl an sozionegativen Interaktionen im Bereich der Futtereinrichtungen. Die Herzfrequenz lag im Warteareal im Durchschnitt im physiologischen Bereich (44,59 ± 11,73 Schläge/min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem traten nicht auf. Der wichtigste Einflussfaktor auf die Untersuchungskriterien war der Betrieb (Fläche, Konzeption, Management). Schlussfolgerung: Unter dem Aspekt der Tiergerechtheit hinsichtlich des Stress- und Verletzungsrisikos durch soziale Interaktionen eignen sich bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management sowohl Fressstände als auch Abrufstationen für Pferde im Offenlaufstall. [Objective: A comparison with regard to animal welfare of feeding stalls and automatic feeding systems for hay and concentrates in group housing systems for horses using parameters of ethology and physiology. Material and method: The observations of animal behaviour took place in 10 stables with feeding stalls and in 11 stables with automatic feeding systems. The field around the feeding systems was divided into three areas with comparable dimensions (waiting area, exit area and inside of the feeding system). 270 horses were individually observed. Parameters of research comprised: threatening behaviour with and without risk of injury, avoiding behaviour, ”chasing away from the feeding place”, as well as heart rate and injuries of the integument. Every group of horses was continuously observed for 24 hours. This observation took place on four different days and comprised six sessions, each of 4 hours. Results: In the waiting area of the automatic systems there were significantly more threatening gestures with and without risk of injuries for each horse and day (8.6 and 3.0, respectively) than in the waiting area of the feeding stalls. In contrast, the horses could eat more relaxed in the automatic systems (1.4 threatening gestures for each horse and day) than in the feeding stalls (3.2 threatening gestures for each horse and day). All together the number of negative interactions in the feeding area of both feeding systems was relatively low. The heart rate was within the physiological range (44,59 ± 11,73 beats/min) in the waiting area. There were no injuries of the integument in correlation with the feeding systems. The most important factor of the observation criteria was the individual group housing system with its different dimension, conception and management. Conclusion: Under the aspect of animal welfare both feeding systems are suitable for horses with respect to the risk of stress and injuries by social interactions and under the condition of proper group housing with professional management.] |

| Abstract | Heart rate, arterial blood pressures, respiratory rate, body temperature, and central nervous system excitement were compared before and after epidural administration of morphine (0.1 mg/kg), butorphanol (0.08 mg/kg), alfentanil (0.02 mg/kg), tramadol (1.0 mg/kg), the k-opioid agonist U50488H (0.08 mg/kg), or sterile water using an incomplete Latin square crossover design in five conscious adult horses. Treatments were administered into the first intercoccygeal epidural space. Significant (P <.05) reductions in respiratory rate were detected after epidural administration of morphine, alfentanil, U50488H, and sterile water. Additionally, significant (P <.05) head ptosis was observed within the first hour after administration of morphine, U50488H, and tramadol, but neither of these changes appeared to be of clinical significance. No treatment-related changes in motor activity or behavior were observed. | ||||

| Abstract | In many social species, relationships within groups seem to be non-random but related to variables such as rank, kinship or sexual attractiveness. The endangered African wild dog Lycaon pictus is a social carnivore that lives in large, stable packs, and intra-pack associations might be expected to display similar patterns. We investigated patterns of coalition formation (support during dominance interactions, and partnership interactions) and resting associations between members of a captive pack of 19 wild dogs. The social organization of the captive pack was similar to that of free-ranging packs in many respects. Polyadic (group) incidents of coalition support were also observed in a free-ranging pack. Patterns of coalition formation in the captive pack were related to rank. Most aggressive interactions involved high-ranking individuals (particularly the alpha, beta and third-ranking males) and coalitionary support tended to reinforce the existing hierarchy. However, there was at least one example of support influencing a successful rank challenge. Support was affected by potential risks and benefits, the latter including dominance through association and revolutionary alliances. An even stronger pattern overlaid associations between pack members: coalitions and resting associations were strongest between members of the same age–sex cohort, and may have enabled the eventual dominance of younger pack members over adults. Among adults, coalitionary associations were sometimes overridden by intersexual relationships. The results from this captive pack suggest that wild dogs are sensitive to differences in competitive ability. This information, in conjunction with strong affiliative bonds between littermates, is used to manoeuvre for position in the social hierarchy. It may also be important during dispersal, in encounters with other dispersing groups of the same sex. Although most features of the social structure of the captive pack were comparable to those of free-ranging packs, aspects such as the influence of relatedness on coalition formation still need to be explored. | ||||
